Casting thev naus laus zis ntawm tsheb Aluminium Log Hub thiab daim ntawv thov kev cia siab ntawm ua npuas hlau hauv Aluminium ua kua lim

Casting thev naus laus zis ntawm tsheb Aluminium Log Hub thiab daim ntawv thov kev cia siab ntawm ua npuas hlau hauv Aluminium ua kua lim
1, nchuav cov txheej txheem thiab cov kev xav tau rau txhuas log hubs
Kev tsim cov txhuas lub log rau cov tsheb siv cov roj rov ua dua tshiab, thiab ua tiav cov khoom siv raw, thiab ua tiav cov khoom siv raw, thiab ua tiav cov khoom siv metycling, thiab ua tiav, thiab ua tom ntej. Nws cov txheej txheem tseem ceeb muaj xws li:
1) SMELTING: Tso cov khoom ntxuav kom huv huv nyob rau hauv lub rauv mel thiab yaj nws ntawm qhov kub kom ua cov kua txhuas. Txhawm rau txhim kho cov khoom siv ua tau zoo, txhuas oxalate yuav tsum tau ntxiv rau cov kev ua kom zoo dua rau cov zog thiab corrosion tsis kam.
2) Casting: Aluminium kua tau sib xyaw dawb thiab txhaj rau hauv cov pwm, feem ntau yog siv qis-siab forging txheej txheem. Lub qub rho tawm qhov tsis xws luag los ntawm kev tswj siab, thaum lub tom ntej siv lub tshuab nqus tsev kom nce ntom ntom thiab kom cov qauv sib dhos.
3) Tswjhwm Zoo: Tom qab txias thiab solidification, lub log hub yuav tau ua kom tau raws li cov kev kho mob hauv GB / T 31203 thiab lwm cov qauv rau lub zog, nkees ua yeeb yam, thiab qhov tseeb thiab tsis zoo.

2, Kev sib tw sib tw ntawm txhuas ua kua lim
Cov Oxides Oxides, Slag Inclusions, thiab npuas hauv cov kua txhuas yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm lub log HUB. Cov txheej txheem ib txwm muaj xws li ceramic mesh lossis fiber ntau cov impurities, tab sis lawv muaj tsis xws li porosity tsawg li tsawg heev. Tshwj xeeb tshaj yog nyob rau hauv high-highting txheej txheem, kev ntws nrawm ntawm cov dej khov ua kua tuaj yeem yooj yim rau lub lim nruab nrab, cuam tshuam rau kev ua kom pom tseeb. Yog li ntawd, txhim kho qhov siab tiv taus kub, siab porosity, thiab cov khoom siv lim ntim ruaj khov tau los ua qhov mob ntawm kev lag luam.

3, cov ntsiab lus zoo thiab pom metration mechanism ntawm cov hlau ua npuas hlau
Ua npuas ncauj hlau yog cov khoom siv ntxeem tau nrog lub porosity ntawm ntau dua 90%, uas muaj ib qho txawv ntawm cov qauv network. Nws cov txiaj ntsig yog raws li hauv qab no:
1) Kev ua kom pom kev ua tau zoo: loj pore loj (txog li 7 millimeters) thiab siab porosity tuaj yeem cuam tshuam cov kua roj macroscopic hauv cov kua dej yooj yim.
2) Cov tshuaj kub siab tiv taus thiab tshuaj lom neeg stability: Npib Ua npuas dej Ua kom muaj qhov kub thiab tsis muaj tshuaj lom neeg nrog kua txhuas kom tsis txhob muaj kuab paug.
3) Lub Zog Tsim Zog thiab Kev Cuam Tshuam: Cov Hlau Skeleton muab kev txhawb nqa thiab tsis yooj yim deformed txawm tias muaj kev ruaj ntseg ntawm cov txheej txheem pom.
Noj ua npuas dej hlau nickel alloy ua ib qho piv txwv, nws tuaj yeem ua kom zoo tshaj plaws ntawm kev ua raws li lub cev: los ntawm kev ua kom tiav oxidation slag suav thiab txhim kho lub purity ntawm aluminium kua. Kev xyaum ntawm Hadan Yiyang Feimeationite Co., Ltd. Siv cov khoom siv ua npuas dej ntau ntxiv los ntawm 20%, thiab cov kab ntawv tsis tau txo qis.

4, Thov kev cia siab ntawm cov hlau ua npuas dej hauv lim ntawm molten aluminium
Txheej txheem ua kom zoo: Ua npuas dej hlau tuaj yeem ua ke nrog cov txheej txheem kev sib xyaw ua ke, rov qab ua tiav kev sib koom ua "lim thiab tsim cov txheej txheem thiab txhim kho cov txheej txheem thiab txhim kho cov txheej txheem thiab txhim kho cov txheej txheem thiab txhim kho cov txheej txheem thiab txhim kho cov txheej txheem thiab txhim kho cov txheej txheem ntau lawm.
Kev tiv thaiv ib puag ncig thiab tus nqi-ua hauj lwm: ua npuas hlau tuaj yeem siv tau los txo cov khoom siv lim cov khoom siv cov qub. Nyob rau tib lub sijhawm, nws cov cwj pwm me me (nrog qhov ntom ntom ntawm 1/3 ntawm cov hlau) tuaj yeem txo kev thauj mus los thiab ua kom muaj zog siv hluav taws xob.
Ntau daim teb txuas ntxiv: Ntxiv rau lub log hub kev tsim, cov ntawv sau ua npuas dej hauv cov roj teeb tshiab, uas tuaj yeem txhawb kev ua lag luam txhuas ntawm cov kev lag luam qub.

5, Thov cov zeem muag
Nrog nws cov qauv sib txawv ntawm cov qauv sib txawv thiab cov kev ua npuas dej zoo, ua npuas dej muab cov kev daws teeb meem tshiab rau kev siv ua kom pom tseeb. Nrog kev nce qib ntawm cov khoom siv thev naus laus zis thiab kev ua kom zoo dua qub, nws daim ntawv thov hauv kev siv tsheb loj, pab cov kev lag luam muaj kev ua haujlwm siab thiab ntsuab. Yav tom ntej, ua ke nrog cov txheej txheem ntse Casting, Fermet Ua Npuas Ncauj Hlau yuav tsum los ua cov khoom tseem ceeb los txhim kho cov khoom tseem ceeb thiab ntxiv cov txiaj ntsig ntawm cov khoom txhuas.
